PDC: Amazon Kindle app coming for Windows Phone 7

Yes, Virginia, there will be an Amazon Kindle app available this holiday for Windows Phone 7.

The Seattle-based e-retailer announced today that the Microsoft mobile platform will get a Kindle app by the end of the year. Like on other mobile operating systems, it’ll be free.

“When you buy a Kindle book, we make it easy for you to get your books on all of the devices you want to read on — your iPhone, iPad, Android-based device, PC, Mac, BlackBerry, and of course your Kindle, Kindle 3G and Kindle DX,” Dorothy Nicholls, director of the Kindle program, said in an Amazon news release. “Kindle for Windows Phone 7 extends our vision of ‘buy once, read everywhere.’

“The app is optimized for the unique user interface of Windows Phone 7, and will include our Whispersync technology, so you always have your library with you and never lose your place in a book as you switch between devices.”

Microsoft first made the announcement this morning during its Professional Developers Conference in Redmond. The software giant also showed a few other new Windows Phone 7 apps: Facebook, Bejeweled and TaxCaster (from TurboTax).
